Patriots' Brady has surgery

A person with knowledge of the operation says Tom Brady has undergone surgery on his right foot.

The surgery for a stress fracture took place Thursday, and the New England Patriots quarterback "is doing good," the person said on condition of anonymity because an official announcement had not been made by the team.

Comcast SportsNet New England reported that a screw was inserted in the navicular bone, one of the small bones on the mid-foot located at the instep.

Brady was listed on the Patriots' injury report with a foot injury for the last eight regular season games and a playoff game, a 28-21 loss to the New York Jets.

Brady led the NFL in passer rating, touchdown passes (36) and fewest interceptions (four). He also threw for 3,900 yards.

l VIKINGS: The new head of the Metropolitan Sports Facilities Commission said that replacing the snow-damaged roof of the Metrodome would likely take five to six months, raising the possibility of disrupting Minnesota's schedule for next season.

Ted Mondale took the oath as chairman Thursday, less than a week after Gov. Mark Dayton made the former state senator his administration's point man on the push for a new Vikings stadium.

"This is the year we do it," Mondale said of the effort to replace the Metrodome as the state's NFL venue.

However, the Vikings have one more year on their lease in the dome, which was damaged by a December blizzard.

The commission is awaiting a report on the extent of that damage, a recommendation on whether to simply repair torn panels or replace the damaged roof entirely, and estimated costs. The report is expected before the end of January.

Mondale said replacing the roof would likely mean five to six months of work. Depending on the timing, repairs could go into late summer and the August start of the NFL exhibition season. The NFL has not yet released the 2011 schedule; it will be announced in April.

l TITANS: Chuck Cecil says that Tennessee coach Jeff Fisher has decided not to keep him as the Titans defensive coordinator after two seasons in which the team ranked among the NFL's worst in yards allowed.
